IEC TC 57 has proposed a new part for IEC 61850 (57/1766/DC): IEC TR 61850-90-20 - Communication networks and systems for power utility automation – Part 90-20: Guideline to redundancy systems. As more application domains are added to the IEC 61850, additional modelling, description and functional capabilities needs to be added to the “core” of IEC 61850. And one of such capabilities is redundancy.
IEC TR 61850-90-14 - Communication networks and systems for power utility automation - Part 90-14: Using IEC 61850 for FACTS (Flexible AC Transmission Systems) data modelling has been published as draft for comments of the industry.
IEC TC 57 proposes a new work item (57/1768/NP) IEC 61850-7-7: Communication networks and systems for power utility automation – Part 7-7: Basic communication structure – Machine-processable format of IEC 61850-related data models for tools (proposed 61850-7-7). Closing date for voting: 2016-11-25.
